IMPROVEMENT IN JINERS GAGES.

Specilioation forming part of Letters Patent No. 4 [,86?, dated March 8, 1864.

Figure l is a perspective view of thecom bined gage; Fig. 2, a vertical section across the head I, showing the thumb-screw F, burr G, )late H, inserted in the wood over the stem A, the sliding mortise gage E, andstems B, C, and D. Fig. 3 shows the four stems removed from the head, placed at different gaging distances or positions. Figs. 4 and 5 illustrate the same when but three stems are employed.

The drawings clearly show the construction, and the operation has all the simplicity of an ordinary single gage.

The advantage is that youhave the mortisegage and that of three or four other gages firmly set in one tool, when working out stuff requiring several gages, each stem being independently adjustable, firmly wedged together, and held in place by the thumbscrew F, burr G, and metallic plate H, resting on the upper stem, A, and mortise-slide E. These several stems can be graduated to inches and their divisions capped with brass, and made after the ordinary manner gages with a single stem are made.

Experience has taught me the necessity of having three or four separate gages at hand ing mortise stem or gage.

on certain work. In order to economize the expense, space'on the bench or tool-chest, and the greater convenience in having all in one tool, I was induced to invent this combined gage. The several beveled sides coming in Contact may be perfectly dat, or fitted together by a tongue and groove, should that be desirable. The nature of the plane beveled sides, however, is such that the pressure of the screw tends to wedge all the stems against the inside of the mortise in the head made for their reception, as will be seen upon inspection of Figs. 2 or 5. From personal experience I hold this to be a desirable article, and of great utility to joiuers, cabinet-makers, Svc., and a tool in constant demand for striking parallel lines of various distances from the outer edge, made adjustable in the manner set'forth by the sliding of the several stems on each other, combined in a single head.

I am aware that there is no novelty in the gage with its four sides, head, screw, and slid- This is common; but I am not aware thatthere are any three or four sided gages in use whose separate sides are adjustable by being formed of independent pieces or stems.

What I claim as my invention, and desire to secure by Letters Patent, is-

A gage the stem of which is comprised of three or four separate stems, each independently adjustable, and held by a single thumbscrew, substantially in the manner shown, and for the purpose specified.
